Abstract

PURPOSE:To make it possible to take out the signals of IC pins in one column through monitor terminals by moving contact levers which are arranged in the direction of the columns, and connection pin-contact parts which are provided at the contact levers to IC contact parts and the monitor terminals. CONSTITUTION:At IC sockets 1 which are used for pin-grid-array type ICs. IC contact parts 2 are embedded in an insulating body 6 so as to meet intervals between the pins of the ICs to be mounted. Monitor terminals 3 comprising conductors are arranged and fixed in the direction of rows at the intermediate positions of the contact pats 2 of the sockets 1. Contact levers 4 comprising insulated bodies are arranged in the direction of the columns at the intermediate position of the contact between the contact parts 2. The levers 4 can be moved in parallel. Pin contact parts 5 comprising conductors are provided. The contact parts 5 are used to connect the contact parts 2 and the terminals 3. The contact parts 5 are in the electric contact state with the terminals 3 all the time. There for, when the lever 4 in the desired column is moved and the contact part 5 is brought into contact with the contact part 2, the input/output signals for one column can be taken out through the terminals 3.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to PGA (PIN GRID ARRAY)
The present invention relates to an IC socket used for a type of IC, and particularly to its structure.

[Conventional technology]

Conventionally, this kind of PGA type IC socket was simply an IC socket.
It only had the ability to implement .

[Problem that the invention attempts to solve]

The conventional PGA type IC socket mentioned above only had the function of mounting an IC, so when monitoring the IC pins, wires were connected between each pin and the check terminal provided on the front surface from the back of the board on which the socket was mounted. etc.

If the IC has a large number of pins, it may be physically impossible to monitor all pins using this method.

An object of the present invention is to provide an IC socket that solves the above problems.

[Means to solve the problem]

In order to achieve the above object, the IC socket according to the present invention includes a pin grid array (PIN GRID ARRA).
In an IC socket used for a Y) type IC, conductors are arranged inside in a matrix, the conductors in the column direction are moved, and the conductors in the row direction are brought into contact with the pins of the IC. It has a mechanism for taking out the input/output signals for the columns to the outside.

〔Example〕

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1(a) is a configuration diagram showing one embodiment of the present invention, and FIG. 1(h)
is the same sectional view.

In the figure, the IC socket L of this embodiment has an insulator 6 and an I
It consists of C contact part 2. The IC contact portion 2 is embedded in the IC socket 1 in a manner that matches the spacing between the pins of the PGA type IC to be mounted. A monitor end P3 made of a conductor is arranged in the row direction at an intermediate position of the IC contact portion 2 inside this IC socket 1 and fixed. Both ends or one end of the monitor terminal 3 are projected to the outside of the IC socket 1. In addition, a contact lever 4 made of an insulator is provided in the row direction at an intermediate position of the IC contact portion 2.
Place. The contact lever 4 can be moved in parallel to the row direction. A conductive pin contact portion 5 is attached to the contact lever 4 to electrically connect the IC contact portion 2 and the monitor terminal 3, and the monitor terminal 3 and the pin contact portion 5 are always electrically connected. keep it in condition.

Next, the operation will be explained. FIG. 2 is an enlarged view of the contact portion of FIG. 1. In FIG. 2, P is used as the IC contact part 2.
1 to P4, old as monitor terminal 3, M2
, and the contact lever 4 is At.

The pin contact portions are labeled A2, and the pin contact portions are labeled C1 to C4. Move the contact lever AI in the direction of the arrow to connect the pin contact portion C1 attached to the contact lever AI to the IC contact portion Pl. Since the pin contact portion C1 is connected to the monitor terminal Ml, the signal from the IC contact portion Pi can be taken out to the monitor terminal. In this state, pin contact portion C3 is connected to IC contact portion P3, and a signal from IC contact portion P3 can be taken out to monitor terminal A2.

When the contact lever A1 is returned to its original position and the contact lever A2 is moved in the direction of the arrow, 1. The signal from the C contact portion P2 can be taken out from the monitor terminal old, and the signal from the IC contact portion P4 can be taken out from the monitor terminal M2.

〔Effect of the invention〕

As explained above, the present invention moves the contact levers arranged in the row direction, and the pin contact portion of the contact lever is moved to the IC.
By connecting the contact portion to the monitor terminal, the signals of the ]C pin for one column can be taken out to the monitor terminal.

Therefore, by moving the contact lever adjacent to the IC pin you want to monitor and connecting it to the IC contact part,
This has the effect of allowing IC signals to be taken out from the monitor terminal adjacent to the pin.
